Adjective and Adverbs

An adjective defines a noun or pronoun: 

• That guy is so rude!

An adverb explains a verb or anything aside from a noun and pronoun:

• That guy talks so rudely!

Adverbs are applied to reply to how questions. Like; 

• How does that guy talk? 
• He talks rudely.

Blossoms smell fresh, or blossoms smell freshly, which is correct? Fresh is right because it depicts the smell of blossoms. Smell freshly shows how a rose smells means blossoms do not have noses, so they cannot smell.
